To all whom it may concern.-

Be it known that we, CHARLES F. KLEIN, of the city of Cincinnati, county of Hamilton, and State of Ohio, and HUGO A. HECKER, of the city of Bellevue, county of Oampbelhand State of Kentucky, citizens of the United States, have invented certain new and useful Improvements in Mangles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

Our invention relates to mangles or ironingmachines for ironing for what in a steamlaundry is technically known as flat work such as sheets, table-cloths,towels, napkins, &c.-and it has for its object to provide a machine simple and easy of operation, with large capacity, and for the finishing of both sides of the goods to be operated upon. This is accomplished by the peculiar arrangement of steam-heated chests and padded rolls and the rotating steam-heated cylinder and apron, whereby the goods to be operated upon are first passed between the chests and pad-rolls 2 5 being carried from oneto the other over a curved plate, thereby ironing the lower side of same, and thence passing between the steam-heated cylinder and an endless apron, whereby the upper side is ironed and, delivered to a receiving-table.

The curved plate above mentioned is preferably perforated, as the heat radiated from the sides of the chest will thereby be allowed to pass upward through the perforations and assist in drying the goods as they pass over it.

An additional feature of our mangle is that small pieces too short to be carried over the abovepla-te may be placed by the operator at the delivery side of the machine on the top of the steam-heated cylinder and beironed only by the action of the cylinder and apron, such piecesusually not requiring more ironing than they would thus obtain. H

We also provide a machine in which the covering of the rolls and apron, which are the parts most frequently requiring renewal, shall be as inexpensive as possible and in which the pressure upon these parts shall be under" simple and'easy control of the operator. To these ends our invention is particularly adapted, as will be seen in the following description.

In the drawings, Figure 1 is a side elevation of our improved machine, the side being the one in which the belt for communicating mo- 5 5 tion to the machine is connected. Fig. 2 is a verticallongitudinalsection ofthe same. Fig. 3 is a side elevation of the opposite side of the machine from that shown in Fig. 1. Fig. 4 is an enlarged top view,'and'Fig. 5 an enlarged side view, of the mechanism for controlling the pressure upon the'padded rolls. Fig. 6 is an enlarged frontview, and Fig. 7 a plan view,

of the mechanism for controlling the movement of the apron. Figs. 8 and 9 are respectively a side and sectional view of the dofferplate on the delivery'end of the mangle. Fig. 10 is a plan view of the apron-controlling mechanism, showing both ends. Fig. 11 is a perspective view of the gearing for controlling 7o the pressure of the padded rolls.

In the drawings, A and A are the main frames of :the machines, which are tied together by the'cross-girths B'and'B.

,G and O are padded rolls constructed of 'v wrought -.iron tubing and covered with felt and canvas,- operating in boxes D and D, which are mounted in suitable recesses in the main frames.

E and E (see Fig. 2) are steam heated 8o chests having polished concave ironing-surfaces to fit the periphery of the padded rolls.

F, Fig. 2, is a curved plate with a polished surface and preferably perforated with a large number of small holes.

' It would be practicable in a machine of less capacity to omit steam-chest E without departing from the spirit of our invention, and for machines of greater capacity it-may be desirable to use two pair of chests, each with 0 its adjusting device, as shown at'Figs: ianne.

G is a box for the reception ofthe goodsto be operated upon, and G is a feed-plateupon' which the goods are laid and straightened to 7 enter into the machine. 7

' H isa smooth-surfaced steam-heated'rotat I ing cylinder or drum of large diameter with relation to the padded rolls and having. the

lower part of. its circumference encircled by an endless apron J of flexible material, such loo as canvas, mounted upon rollers K, K, K and K and having a roller K pressing upon its front side to deflect the apron, giving room for inserting the edge of the table L as far under the roll K as possible.

M is a doffer-plate of sheet metal attached to circular collars M, (see Fig. 9,) which are pivotally mounted upon the innercnds of the journal-boxes M N N are journalboxes for the roll K, mounted upon screws N N, operating in bearings N N and connected through wormgears N N' and the shafts N to the handwheel N through the medium of which the roll is traversed backward or forward, the object being to take up the slack in the apron, or vice versa, leaving the apron in a slack condition when the machine is not in operation. In practical experience it is found that aprons of this class have a tendency to shift sidewise from one end of the roller. To obviate this, the journal-bearings O and O for the bar or roller K are pivotally mounted upon swivel sectorarms and O by means of studs 0, formed on or extending laterally from the sides of the bearings O and 0 said swivel sector-arms being pivoted or hung at 0 on supports 0 projecting from the girth B. Sector-teeth O are out upon the inner ends of the swivel-arms 0 0 which are engaged by worms 0 of the same handthat is, both right handed or both lefthanded wormsmonnted on the shaft 0, to which a hand-wheel O is attached. If the apron J has a tendency to run toward one side of the machine, the hand-wheel O is rotated, so that through the medium of the worms on the shaft O the swivel-arm on that side is thrown out, while the corresponding swivel at the other end is thrown in, thus shifting the apron back into proper position.

Referring to Figs. 4 and 5, will be seen the mechanism by which the pressure of the padded rolls upon the heated chests is controlled. D D are the journal-boxes within which the rolls are mounted at each end, operating vertically in suitable recesses in the frames A A. The boxes each have a projection D D formed upon their upper surface, to which is connected an eyebolt D passing through the levers D D with lock-nuts D upon their upper ends. The levers are pivotally connected at one end to suitable lugs D D on the frames, the other end being pivotally connected to a square or rectangular block D D, having a hole through its center, through which passes the upper and threaded end of a rod D D and having a lock-nut D D upon each side of the block. A portion 24 of this rod is formed in a square shape where it passes through the frame at D to prevent its turning. The lower end of this rod is also threaded and passes through the Worm-wheels D D, which are threaded to suit. These wheels D D are in mesh with the worm wheels D mounted upon a shaft D with a hand-wheel D for revolving the same. It is evident that turning this hand -wheel will cause all the rods D D to be elevated or depressed simultaneously, according to the direction in which it is rotated, care being taken to have one of each pair threaded with a right-hand thread and the other of each pair having a left-hand thread. The levers D D are formed witha cup-shaped recess in their central part, in which is placed a spring D bearing upon the journal-boxes D D,by which the pressure is made yielding, allowing goods of difierent thicknesses to pass between the rolls and chests without constantly altering the position of the levers.

Referring to Figs. 3, 8, and 9,11 represents levers mounted pivotally at each side of the frame at M and having in their upper ends journalboxes M in which is mounted the roll K These journal-boxes are fitted in square slots in these levers M to prevent their turning. One end of each box is turned on its inside to a cylindrical shape and has fitted thereon a circular collar M, which may be rotated thereon and secured at any desired point by the set-screws M To these collars is fitted a curved plate M, called a doifer-plate, whose object is to strip the goods as they reach this point from the rotating cylinder H and cause them to pass over the roll K and down upon the table L, Where they are received by an operator and taken away. A doifer-plate such as this is not an entirely new thing; but we believe the method of mounting same on the journal-boxes in a pivotal manner is new, whereby the plate may be adjusted so as to just touch the rotat ing cylinder.

It will be understood, of course, that the rolls 0 C and the cylinder H are driven at the proper rate of speed by suitable power, and we have shown in the drawings the trains of gearing and the band-wheel by means of which the ironing-rolls and ironing-cylinder are rotated. We have not, however, lettered or described this driving-gearing, as the con struction and operation will be evident from an inspection of the drawings.

The operation of the machine will be evi dent from the foregoing description. The articles to be ironed are fed under the padded roll 0, over the perforated plate F, and un der the padded roll 0, by which operation they are thoroughly ironed on one side by contact with the steam-chests E E under pressure of the padded rolls, the heat from the steamchests rising through the perforated plate taking up the bulk of the water in the articles. The goods then continue 011 between the endless apron and the steam-heated cylinder H and by contact therewith are ironed on the other side and dried, whence they are delivered by the doffer-plate to the delivery-table L.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

1. In a mangle, a plurality of padded rolls,

ICC

2. In a mangle, the combination with a supporting-frame, a pair of padded rolls and heating-chests against which said rolls run, journal-boxes for said rolls m'ovably mounted in said supporting frame, levers pivoted to the frame onoppo'site sides of said rolls,

springs between said levers and journal-- boxes, rods attached to the free adjacent ends of-said levers, threaded nuts on said rods,

and a worm-shaft arranged to simultaneously engage and operate said nuts to move said rods and regulate the pressure of said springs.

3. In a mangle, the combination, with a rotating cylinder and an endlessapron in contact therewith, a series of rollers over which said apron travels, journal-bearings for one of said rolls having cylindrical portions with rotatable collars mounted thereon, set-screws for holding same, and a semicylindrical doffer-plate mounted on said collars, whereby said dofEer-plate may be adjusted for readily stripping the ironed article from the cylinder, substantially as shown and described.
